l, itknowi that I, Enwauo J, Wrcctxs, ac itizei i-= of the'linited States, rsiding at Chicago, in thecounty of Cook andStateof Illino s, haveinvented a new and useful lin n ovenient ,in l\l ethods of Preparing Liquid .Il'ydrocarbon for Combustion, of which the following. is a specification.

The object of my iliYGlitlOItiSlO provide a novel and coinpai atively inexpensive method jot preparing 'liqi'iid hydrocarbon for combustion, andflmore particularly kerosene and the heavier hydrocarbons (though it is also applicable to the lighter hydrocarbons, or nurtures, such, as gasolene) whereby in feeding the same to a burner, as the point of combustion, it shall be rendered, while traversing its course thereto, readily igiiitible at the burner and so thoroughly-combustible as to emit a blue flame of high incandeseing ability.

My inventioiiinay be best explained by reference to means suitable for practicing the method, such means being illustrated in the accompanying drawing, which shows, by a broken and sectional view in side elevation, partly diagran'iniatic, a desirable form of apparatus for the purpose.

The supply of liquid hydrocarbon, such as kerosene, may be containedin a tank 2 and is preferably maintained under pressure, and it 18 also preferred,'but not necessary for the practice of my invention, to

employ air under pressure -for use in the "manner hereinafter described, forwhich purpose an air-pressure supply-tank is shown at 3 provided with a nipple 4- at which to connect an air-pump (not shown).

' which may'a-lso supply the pressure to the tank 2, which communicates with the tank 3 through a valved hose-connection 5. An air-pipe 6 leads horizoiitallyfrom awallbracket 7 and terminates at its advance-end in a perforated plug forming the spraying nozzle; and it has a valved hose eonnection 411 near its opposite end with the air-pressure tank 3. A tube 9 of small bore extends centrally through the air-pipe, terminating in the spraying-nozzle 10 and communicating at its inlet-end, through a valved hose 11 with the tank 2. The burner12 is of the Bunsen type. Its horizontaltubular section 13 is in alinement with the nozzle- 10, but is separated therefrom by an airspace 14 of considerable width and forms supported by a metal fingl and mixing therewith.

:l'm'i entering the chamber 13, and it carries with it into the latter enough more air from the atmosphere to renderthe resultant product completely combustible or approximately By' coursing the mixture through the chamber 3 the particles of kerosene become more and more broken'up and the intimacy of their commingling with air is so enhanced as to reduce the product discharging from the mixing chamber'into the burner-section 13 to a readily igi itible condition, the flame, uponignition, b'eing blue and instan "EDWARD J. wme'msor CI-IiCAGO', imitators, ASSiGNOR, BY'MEsiv'n assienman'rs; rro

taneously incandescing the mantle. More a or less of the heat of combustion is radiated from the point of combustion'a-nd from the mantle into the'chamber 13 and serves to crack the"; particles of hydrocarbon, meaning to break up the hydrocarbon molecules; and as the burner becomes heated, its wall conducts the 'heat to-the section 13 to exert its distilling 'infiuence'on the mixture in the chamber and supplement the cracking and distilling action thereon of the radiant heat from the flame.

An importantfeature of my improvement, which constitutes a principal element ofits departure in the art, is that of spraymg the hvdrocarbon'in an unheated condition in its course to-the burner, into the atmosphere to vaporize it while cold and mix air with the -vapor,- thus avoiding .any heating of the liquid hydrocarbon before it has been vaporized andmore or less intimatel mixed with air; whereas, in the prior ar the liquid hydrocarbon is sulnected to th influence of 1n its lcourse' to or at the spraying- .n'ozzleor' point of s ray-discharge,.and the heat-cracks the hy ro'carbon and tends to produce the deposit of carbon from its con-. 5- stituents, causing the latter to'clog the passages and obstruct the flow.- B keeping heat; away. from'the kerosene unt' its vapo i rization-and intimate mixture with air have been efiected, the cracking action is avoided its possible carbonizing referred to, or

' cokin willcaus'e no harm, and, moreover, the so 1d particles of carbon then remain in the resultant product are consumed in the flame. I

is: As will be understood by. those skilled in theart to which my invention relates, the "product, of cold' yaporization acquires great kinetic energl; glue to 'heat-' r'oducing ac- ;tion, and the oiijrlijlizable particles are split zgt upinto smaller and more ,volatilebodies, re-

sulting in a liqino eneous mixture of gas, vapor and les'serdensity, but of I greater yolum'e thanthe primary mixture.

'-'What I claim-as new and desire to secure 25 by Letters Patent, is-

1. .The methodof preparing hydra carbon for combustion, which consists in 2. The method of, preparing'liquid hydrocarbon for combustion, which consists in conducting separately liquid hydrocarbon and air, both in unheated condition, to a point of mixing the two while in such condition, spraying the unheated mixturein its course to the point of consumption into the atmosphere, thereby atomizing it while cold and mixing more airwith the resultant fluid, and thereafter subjecting the mixture, in said course, to the heat generated at the point of consumption and thus heatin it.
